Question

find the value of x
please give the answer with full explanation​

Answer 1

Answer: 120 degrees

Step-by-step explanation:

First find the total interior angle sum

Therefore, (5-2)180=540

Therefore, the total angle sum is 540

now find the interior angles so we have x+50+x+{180-50}+{180-60}

We know that angle b and c are linear pairs.

Therfore we get, 2x + 50 + 130 + 120

= 2x + 300

We know that,

2x+300=540

Thus, 2x=540-300=240

Therefore x=240/2=120

thus the answer is 120
